QR Codes

QR Codes are 2-dimensional bar-codes which may be encoded to carry a variety of information that is then read using a cell phone or other camera-based device. Gravatar provides simple QR codes which contain a link back to the main profile page for the requested profile.

Base Request

Making a QR request is likely to follow these steps (assuming you have an email address already):

Append .qr to that URL to indicate that you want the results in QR Code format

Once you have done the above, you should end up with a URL that looks something like this:

https://www.gravatar.com/205e460b479e2e5b48aec07710c08d50.qr

When you request that URL (you can do it in your browser) you should get a QR Code image in PNG format that will link directly to the profile page of the requested user when scanned by a QR-compatible device.

Request Options

The QR Code format supports a single option/parameter, size (or s), which is used to specify the edge length of the desired QR code image. Since they are square, you only need to specify a single pixel-based value:

As with all profile data formats, profile requests will only resolve for the hash of the primary address on an account. Users may have multiple addresses on a single account, so while a Gravatar image request may return a result, a profile request for the same hash may not.
